HEX Here4 Multiband RTK GNSS GPS Module

The HEX Here4 Multiband RTK GNSS module is a high-precision navigation module engineered for centimeter-level accuracy in drone and robotics systems. Powered by the u-blox NEO-F9P chip, it supports all major GNSS systems, including Beidou, Galileo, GLONASS, GPS, and QZSS, using multi-frequency DGNSS signals. With dual-band L1/L5 RTK capabilities, it quickly achieves a stable RTK Fix, ensuring consistent and real-time RTK navigation.

Unlike standard GNSS modules, Here4 also integrates navigation functions, RC inputs, camera triggers, and PWM outputs, enabling tight control and mapping precision. It uses CAN FD for low-latency communication and features a dual-band Taoglas antenna for enhanced signal acquisition. Built on the AP-Periph platform, the device supports ArduPilot, Pixhawk, and CubePilot ecosystems. Ideal for drone pilots, OEM integrators, and autonomous systems seeking centimeter-level navigation in complex conditions.
